I-gel喉罩在老年無牙齒患者全身麻醉中通氣效果的臨床觀察
[Abstract]:Objective to observe the application of I-gel laryngeal mask in general anesthesia of elderly patients without teeth by comparing the effect of laryngeal mask ventilation with that of the elderly patients with normal teeth, so as to provide reference for clinical practice. Methods in this study, 60 elderly male patients undergoing inguinal herniorrhaphy under general anesthesia were selected as experimental subjects, all received from May 2014 to May 2015 in the affiliated Hospital of Hangzhou normal University. There were 30 cases in each group. According to body weight, laryngeal mask type was selected, and the laryngeal mask was placed after anesthesia induction and mechanical ventilation was carried out. The mean arterial pressure and heart rate were recorded before induction (T0), immediately after placement of laryngeal mask (T1), 3 min (T2) and before pulling out laryngeal mask (T3), immediately after pullout (T4) and 3 min (T5). The time and times of laryngeal mask placement, the classification of laryngeal mask, airway seal pressure, related complications and blood gas analysis were recorded, and the ventilation effect of patients before and after operation was compared. Results the laryngeal mask implantation time and times in NT group were more than that in T group, but the difference was not statistically significant (P0.05). There was no significant difference in the success rate of laryngeal mask placement, the position of laryngeal mask, the airways seal pressure and air leakage in the two groups (P0.05). The hemodynamics of the two groups was stable when the laryngeal mask was inserted and pulled out, and there was no significant difference in other complications between the two groups (P0.05). Conclusion I-gel laryngeal mask is mirrored anastomosis with perilaryngeal tissue after ventilation, which can effectively reduce the compression of perilaryngeal tissue and provide a safer anaesthesia environment for elderly patients. It can effectively prevent hemodynamic fluctuation caused by ventilation and reduce the incidence of adverse events during general anesthesia in elderly patients without teeth, which plays an important role in clinical practice.
